Eh

checking behind that river when checked to is just too weak imho. I mean yeah, after the river CR, imma go ahead and say yeah, mizor prolly has quads. But the flop call and turn donk, i mean, there hasn't been enough action really to convince me he's got the nizzles...I think your gonna see hands like 88 and even A6 or even AJ here often enough that you shouldn't fold to turn donk, and i think lots of worse hands than JJ will call your river bet too, so i wouldnt check behind if checked to, unless i was damn shure about my read on mizor...

After the river CR, i suppose folding isn't a crime but i proll wouldn't even fold, and i fold more rivers than most limit players...justify the call by sayin its worth a BB to establish a solid read against a decent regular...?

I can't put the CR on the river as a bluff (or quads either). i can see a lot of hands that's he playing this way that you beat (and a couple that you don't). In the end. I like the play and I'd call the river CR. If for no other reason then to get a read on the guy (the hiccup). If you win (which I think the odds are great enough that pot odds dicatate the call on the river) then great, if you don't, well you have a tell that is powerful the next time your in a similar situatioin with this guy...remember him either way

I agree. I probably lean toward a fold with the K out there, but lean towards a call without it. I see him more likely checking a K than chancing you checking behind if he has a Q.
